c# - add item to dropdownlist -

i'm trying add together item dropdownlist oracle datareader, maintain getting error states line has invalid arguments.

can specify text , value? in case, want them same value coming datareader.

tref.items.add(new listitem(dr["t_ref"], dr["t_ref"]));

listitem can take 2 strings parameters, passing 2 objects. seek converting dr object string:

tref.items.add(new listitem(dr["t_ref"].tostring(), dr["t_ref"].tostring()));

alternatively cleaner:

var t_ref = dr["t_ref"].tostring(); tref.items.add(new listitem(t_ref, t_ref));
